Subject: makepkg: check all integrity sums found in the PKGBUILD

Currently we use the INTEGRITY_CHECK array from makepkg.conf to limit both
the integrity sums generated and checked. It doesn't make a whole lot of
sense to ignore integrity sums that are present in a PKGBUILD, so this patch
will enable checking any that are available, but will only print a warning
about missing sums for those types found in INTEGRITY_CHECK.

It also adds a slight optimization of checking for openssl- we only need to
check once now because we use the same program for all checks.
